The compliance work that built your firm is being commoditized. The Big Four are accelerating it.
Continuous compliance on a subscription is the service to sell. Real-time financial oversight takes the place of the annual audit, and ongoing tax position management takes the place of year-end preparation. The firm uses AI for the data work and charges for its judgment. The client pays every month, and the work is still compliance.
What’s happening
Top professional services firms have made more than 100 AI agent partnerships, investments and acquisitions since 2023 (CB Insights, September 2025). EY launched its agentic platform with 150 AI agents for 80,000 of its professionals, starting with tax (EY, March 2025). These are production systems at scale, aimed squarely at the compliance work that mid-market firms depend on.
The downstream effects are already visible. PwC cut 5,600 jobs in the year to June 2025 (Financial Times), and PwC US plans to cut entry-level hiring by nearly a third over three years (Business Insider). That is not a firm struggling. It’s a firm that no longer needs the same number of people to produce the same output. When those efficiency gains reach clients as lower-fee expectations, every firm in the market feels the compression.
Tax preparation, bookkeeping, and basic audit work are following the same pattern as legal document review: AI handles the production, and the human role shifts to review and judgment. The firms that built their revenue on compliance volume are watching that volume become less valuable every quarter. Thomson Reuters data from 2026 shows tax firms lead all professional services sectors in GenAI adoption, and the top use cases are the core of compliance work: tax research, document summarization, bookkeeping, tax return preparation. The work that built the firm is the work the tools do first.
The squeeze comes from below as well as above. This past season, firm owners in practitioner forums traded notes on consumer platforms promoting flat-fee, full-service preparation at prices that undercut mid-tier firms on returns that used to be safely professional work. The same threads described longtime clients leaving over increases of a few hundred dollars. The floor under compliance pricing is being set by software companies that can afford to lose money on any single return, and the returns they can handle competently get more complex every year. A firm that stays in the volume-compliance business is now priced between the Big Four’s AI agents and a consumer platform’s flat-fee promotion.
Why the obvious responses don’t work
“Automate to reduce costs”
Your clients see the same automation you do. When they know AI can do the work, they expect lower fees. Automating compliance work without changing what you sell means you deliver the same commodity faster and cheaper.
“Add AI branding to existing services”
Relabeling your tax prep as ‘AI-powered tax prep’ is not repositioning. Clients aren’t paying more for AI on top of compliance. They’re paying less because AI makes compliance easier.
“Focus on complex compliance work”
The complexity threshold rises every year. EY’s 150 AI agents already handle tax data collection, document review and compliance work for 80,000 of its professionals (EY, March 2025). What counts as ‘complex enough to need a human’ keeps shrinking.
What’s working instead
The firms getting ahead of this are shifting from periodic compliance to continuous monitoring, trading annual audits for real-time financial oversight and year-end preparation for ongoing tax position management. This is a fundamentally different offering: subscription-based, proactive, and built on the premise that AI handles the data work while the firm provides the judgment. It’s also worth more: in the 2024 CPA.com and AICPA PCPS Client Advisory Services Benchmark Survey, the firms earning significant revenue from CFO-level advisory work had more than 30% higher monthly recurring revenue.
The way out is to stop optimizing the old model and sell new services built on what AI can’t do. We find out what your clients will pay for, then build the AI that delivers it. Start with a pilot: in two weeks, a working first version tried on your own client work, then a decision on production. Or start with a plan for the whole firm.

88% of organizations adopted AI. Only 6% see real earnings. The 6% didn’t buy different tools. They redesigned the work and repriced it.
